cura 4.6.1 e retraction


Recommended Posts

Posted (edited) · cura 4.6.1 e retraction

Hello everyone, I have a fairly serious problem, in the machine setting, on the starting script of the print eg:
G21; metric values
G90; absolute positioning
M82; set extruder to absolute mode
G28
G1 X0 Y0
G92 E0; zero the extruded length
G1 F200 E20; extrude 3mm of feed stock
G1 E-2
G92 E0; zero the extruded length again
G4 P6000
The retraction is not -2mm but becomes -20mm why?

    what do you mean by "The retraction is not -2mm but becomes -20mm"?

    I mean that if I set a retraction of the filament of -2mm then the SW does not do it but it portrays me a lot more than 2mm I also arrive at -20mm

    Why should deleting G92 E0 solve the problem?

    G1 F200 E20
    G1 E-2

    because the e-axis moves (slowly) from E=20 to E=-2 (22mm backwards)

    Those are absolute coordinates like set with M82 a few lines above.

     

    Here is a quite comprehensive gcode overview: https://reprap.org/wiki/G-code

    perché l'asse e si sposta (lentamente) da E = 20 a E = -2 (22mm all'indietro)

    Quelle sono coordinate assolute come quelle impostate con M82 poche righe sopra.

     

    Ecco una panoramica del gcode abbastanza completa: https://reprap.org/wiki/G-code

     

    everything works, it was my mistake, sorry for the
      time that I made you waste

    It's okay.  You just helped the next person who googles about this same problem.
